Back in 2016, researchers claimed Dragonfly 44 was a "failed" Milky Way — a galaxy with a huge dark matter mass but almost no stars. Now, on closer examination, that claim has fallen apart.
From the forces that keep athletes twirling and sliding, to the weird laws governing the world of the very small, to the far-out concepts of time travel and alternate universes, physics covers a lot of interesting territory. Here, Live Science keeps you abreast of all the fascinating physics discoveries.Physics
If the Higgs boson really is decaying into pairs of muons in the Large Hadron Collider, that's a big deal for particle physics.
Neutron stars are like the most efficient thermoses in the universe, filled with hot noodle soup. Here's how, over the course of millions of years, they cool down.
A new test of Albert Einstein's theory of general relativity has proved the 20th Century physicist right again, this time using a supermassive black hole.
This supermassive black hole gobbled up a star in full view of Earth's telescopes, and could unlock secrets of how these monsters feed.
In one upside-down, hypothetical version of the universe, a bizarre type of black hole could exist that is stranger than an M.C. Escher sketch: charged black holes.
The magnetic fields are more than a thousand times stronger than the magnetic field used in MRI machines..
Something pulled the outer layer of Cassiopeia A off before it detonated to form this gorgeous supernova. But what?
The Nobel Prize in physics has been awarded to three scientists for their work involving one of the cosmos's most mysterious, darkest, secrets — black holes.
A viable nuclear fusion reactor — one that spits out more energy than it consumes — could be here as soon as 2025.
Something is showering gold across the universe. But no one knows what it is, and key theoretical explanations are falling apart
The rubber ducky comet is glowing, but you can't see it. New analysis of data from the Rosetta probe shows an ultraviolet aurora all around the speeding object.
Physicists have figured out how objects traveling through a superfluid can exceed a critical speed limit.
Earth has a small new moon coming, but it might have been made by people in the 1960s. It will take closer observations to know for sure.
Two experiments hunting for a whisper of a particle called a dark boson that prevents whole galaxies from flying apart recently published some contradictory results.
Phosphine, a chemical long thought to be a signature of life, is floating around in the clouds of Venus. How did it get there?
